## Context
As per PR title - flags the HA toggle in project creation form behind a
flag in enabled-features
Behaviour should be status quo for both staging and prod

## Summary by CodeRabbit
* **New Features**
* Added a high-availability option to the project creation flow for
eligible accounts when the feature is enabled.
* The option is available through controlled feature configuration.
<!-- end of auto-generated comment: release notes by coderabbit.ai -->
When the High availability (Multigres) toggle is enabled in the New
Project form, the Compute size dropdown now offers only **Large** and
the form value is forced to `large`. Previously HA projects showed the
same micro/small/medium options as regular projects.
**Added:**
- `HIGH_AVAILABILITY_INSTANCE_SIZE` constant (`'large'`) alongside the
other `HIGH_AVAILABILITY_*` constants
**Changed:**
- `ComputeSizeSelector` watches `highAvailability` and renders only
Large when it's on (hiding the "Larger instance sizes available after
creation" row); the `cloudProvider` read is now a reactive `useWatch`
instead of a render-time `getValues()`, so the list re-filters when HA
forces the provider to `AWS_K8S`
- `HighAvailabilityInput` forces `instanceSize` to `large` when HA
toggles on and restores the previously selected size when it toggles
off, alongside the existing `dbRegion`/`cloudProvider` handling
- The compute size and region selects ignore Radix's spurious
`onValueChange('')` — Radix emits it when a select's value and option
list change in the same tick, which wiped the forced value (details in
the inline comments)
- HA projects skip the "Confirm compute costs" modal on submit — HA is
free during Alpha, so the forced large size shouldn't trigger the
$110/mo confirmation
## To test
- On a paid org, open the New Project form: with HA off, the Compute
size dropdown shows micro/small/medium plus the disabled "Larger
instance sizes available after creation" row
- Toggle High availability on: the dropdown shows only Large, the
trigger reads "large / 8 GB RAM / 2-core CPU" (not the placeholder), the
region locks as before, and the footer shows $110/m
- Check the network tab: the `available-regions` request goes out with
`desired_instance_size=large` and returns 200 (no request with an empty
`desired_instance_size`)
- Select medium first, toggle HA on then off: medium is restored (same
for other sizes); rapid toggling shouldn't leave the field blank
- With HA on, submitting goes straight through without the "Confirm
compute costs" modal; a non-HA medium project still shows it

## Summary by CodeRabbit
* **New Features**
* High-availability projects now automatically use the required
dedicated instance size.
* Disabling high availability restores the previously selected instance
size.
* Compute size options are filtered based on cloud provider and
high-availability settings.
* **Bug Fixes**
* Prevented accidental clearing of compute size or region selections
during option updates.
* Compute-cost confirmation is no longer required for high-availability
projects.

## Summary
- Move High Availability into the standard project creation settings
above Compute, gated by the `instances.high_availability` entitlement.
- Mark the option as Alpha and explain that it is free during Alpha for
up to two projects.
- Enforce the supported HA configuration: `AWS_K8S`, Postgres 17 on the
`ga` release channel (no custom version is sent — the API resolves the
image), and the environment-specific local/staging region restrictions.
- Show eligible locations in a dedicated **High Availability Regions**
group.
- Preserve the existing Advanced Configuration availability rules and
additionally hide the section while HA is enabled.
- Restore the previous provider and Postgres settings when HA is
switched off.
## How to test
1. Go to create a new project
2. Ensure you have access to high availability (e.g. on local)
3. Toggle high availability on and note how the project form restricts
settings listed above

## Summary by CodeRabbit
* **New Features**
* Added High Availability to project creation with Alpha warning
labeling and improved switch accessibility.
* Constrains region selection to compatible High Availability regions
and enforces HA-specific engine/release settings.
* Disables/hides custom PostgreSQL version selection when High
Availability is enabled (and omits HA custom request payloads).
* **Bug Fixes**
* Improved persistence of selected PostgreSQL version and region across
data reloads and configuration panel reopen/toggle.
* Restores region when form state temporarily drops values during
remounts.
* **Tests**
* Expanded end-to-end coverage for HA UI, region grouping, and
submit/payload restoration behavior.

Hides the "Multigres" term from user-facing surfaces — it's the tech
powering High Availability projects, but "High Availability" is the only
term users should see for now (per Slack discussion with Saxon/Ivan).
**Changed:**
- High Availability badge hover card (project overview) no longer says
"Driven by Multigres"
- Project creation HA toggle description drops the Multigres name +
multigres.com link, keeps the informational copy
- All schema dropdowns now hide the `multigres` schema on HA projects,
by wiring in the previously-unused `filterSchemasForHighAvailability`
helper:
- `SchemaSelector` (shared — Table Editor, Functions, Indexes, Triggers,
Schema Visualizer, etc.)
- `ExposedSchemaSelector` (API settings → exposed schemas)
- `EnableExtensionModal`, `CreateIndexSidePanel`, `ForeignKeySelector`,
`WrapperTableEditor`, Integrations install sheet `AdvancedSettings`
- SQL editor schema autocomplete (`useAddDefinitions`)
- Schema list computations in the touched components are now memoized
(incl. stabilizing `SchemaSelector`'s `excludedSchemas` default so the
memo actually holds)
**Added:**
- Unit tests for `filterSchemasForHighAvailability` /
`resolveHighAvailability`
- MSW component test for `SchemaSelector` asserting `multigres` is
hidden on HA projects and still shown on non-HA projects
The filter is HA-gated on purpose: a self-hosted/non-HA user with their
own schema named `multigres` still sees it. The flag-gated Multigres
option in Logs is intentionally untouched — that exposure is kept for
the Multigres team's debugging (separate track).
## To test
- On an HA project (`high_availability: true`): hover the High
Availability badge on project overview — no "Multigres" mention; open
schema dropdowns in Table Editor / Database pages / SQL editor
autocomplete — no `multigres` schema
- Project creation with HA entitlement: toggle description has no
Multigres wording/link
- On a non-HA project: schema dropdowns behave as before
<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit
* **Improvements**
* Made schema dropdowns and related selectors high-availability aware
across extensions, indexes, integrations, SQL editing, API exposed
schemas, and relationship editors.
* Updated project high-availability UI text and badge hover description
to remove outdated branding and clarify horizontally scalable Postgres
architecture.
* **Tests**
* Added coverage to ensure the schema “multigres” option is hidden/shown
correctly based on high availability, and validated high-availability
value handling.

## Context
Changes here aren't public facing - we're just shifting some internal
only fields on the new project page to consolidate them into the
"internal-only" collapsible
Mainly to improve clarity from our POV RE what fields do users see and
the general look of the new project form
<img width="727" height="558" alt="image"
src="https://github.com/user-attachments/assets/7d8f2915-3a81-4d9d-a067-cd45c1725726"
/>
So everything that's not within the collapsible are essentially fields
that users will see on prod. The changes here also subsequently
deprecates the use of 2 feature flags on the new project page:
- `showPostgresVersionSelector` -> replaced by new flag
`newProjectInternalOnlyConfiguration`
- `enableFlyCloudProvider` -> was used to control the visibility of the
cloud provider field, now replaced by
`newProjectInternalOnlyConfiguration`
<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit
* **Refactor**
* Reorganized project creation form layout and field ordering for
improved structure.
* Updated project resume flow with refined confirmation modal UI.
* Simplified cloud provider selection interface.
* Streamlined high-availability configuration presentation.

## Problem
We used to have a `_Shadcn_` suffix for all the shadcn form components
because we also had `formik` form components.
This is not needed anymore.
## Solution
- Remove the suffix
- Update all usages
